Same dilemma, but you know if anyone has pressed blue yet
Everyone makes their choice in order, not at the same time. Your turn has come. You dont know your turn number.
There is a light bulb that turns on after the first person in the world has pressed blue.
If its NOT on when your turn comes, that means no one has pressed it yet.
Will you still press blue, if you are normally a blue presser in this dilemma?
